The Disney Fantasy cruise ship had to head back to Port Canaveral shortly after setting sail Saturday night when two passengers suffered medical emergencies on board, officials said.

A 6-year-old child with diabetes had to be taken to a hospital for treatment. Also, a 77-year-old man with a heart condition was hospitalized after complaining of chest pains, said Rosalind Harvey, spokeswoman for the Port Canaveral Police Department.

The ship initially left the dock at about 5 p.m. but docked again at about 8:30 p.m. to get medical attention for the two passengers' pre-existing conditions.

The ship has since set sail again to take the other passengers on their seven-day Caribbean cruise, a Disney spokeswoman said.
